Application filed May 23, 1907; Serum. 375,869.

To all whom it may concem:

Be it known that I, HENRY M. Frsx, a citizen of the United States, residing at Pella, in the county of Marion and State of Iowa, have invented a new and useful Improvement in Traveling Capstans, of which: the followin is a specification.

' The ject. of this invention is. to provide an improved construction for traveling capstans.

A further ob ect of this invention is to provide improved means for raising and lower ing the anchor of a traveling capstan;

A further object of this invention-is-to provide improved adjusting means whereby a portion of a traveling capstan intermediate of the supporting wheels thereof may be raised and lowered.

Further objects of my invention will appear in the followingdescription.

My invention consists in the construction, arrangement and combination of elements hereinafter set forth, pointed out in my claims and illustrated by the accompanying drawing, in which- Figure 1 is a side elevation of the machine in position for transportation; Fig. 2 is an opposite side elevation of the machine in like position. Fig. 3 is a plan of the machine.

ig. 4 is a cross-section on the indicated line 4'4 of Fig. 2. Fig. 5 is a cross-section on the indicated line55 of Fig. 2. Fig. 6 is a perspective of oneof the anchors employed in the machine. 35 v In the construction of the machine as shown the numerals 10, 11 designate side barsof amain frame, which side bars are connected by any desired number of cross bars- 12. Arches or trusses 13, 14 are fixed. at their ends to the ends of the side bars 10, 11 and are sprung above said sidebars. The side bars 10 11 and arches or trusses'are connected' by any desired number of struts 15. The rear end portions of the side bars 10, 11 are carried by supporting traction wheels 16, 17. Hounds 18, 19 are pivoted at their rear ends on' the side bars 10, 11 at alining points considerably to the rear of the forward ends of said side bars. Each hound is arched upward and is braced by a truss rod 20 and any desired number of struts 21. 24, each formed of parallel bars connected at theirupper andlower ends, are fixed to and rise from the side bar 10 and receive and embrace the hound 18. The guide 22 is also fixed at its upper end to the arch or truss 13.

Guides 22, 23,-

The guide 24 is of materially greater hei ht than the other guides and is provided wit a plurality of holes adapted to receive a bolt 26,

which bolt also extends through the hound 18 and connects said hound ad ust/ably to the guide. The guide 24 preferably is pivoted at its lower end on the side bar 10 to provide K a flexibility for, urpose of adjustment of the parts connecte thereby.

Guides 27, 28, 29, each formed of parallel bars connected at their upper and lower ends,

are fixed to and rise from the side bar 11 and receive and embrace the hound 19. The guide 27 also is'fixed at its upper end to the arch or truss 14. The guide 29 is of the same height as the; guide 24 and also is provided with a plurality of holes30 adapted to re-. ceive a bolt 31, which bolt also extends through the hound 19 and connects said hound adjustably to the guide. 29 preferably is pivoted at its lower-end on the side bar 11 to provide a flexibility of the parts connected thereby. The guides 24 and 29 may be braced together across the machine in any desired manner. The forward end portions ofthe hounds 18, 19 are connected by a cross bar 32 and said cross 'bar is carried by and pivoted to a bolster 33.

The bolster 33'is carried by an axle 34, and said axle in turn is carried by guiding supporting wheels 35, 36. The central portion of the bolster and axle is connected by braces 37 to the hounds 18, 19. Anchors 38, 39 are provided and are bifurcated in their upper ends and beveled under at their lower ends. The bifurcated upper ends of the anchors 38,

39 straddle and are 'pivoted to the forward ends of the side bars 10, 11. incline downward and rearward fromtheir pivotsand are formed with slots 40 near their lower ends. Links 41, 42, curved throughouttheir lengths, are inserted and pivoted at theirlower ends in the slots40 of the anchors 38, 39. The links 41,. 42 extend upward from the anchors through slots (not shown) in the side bars 10, 11 and are secured by bolts or .pins 43, 44 mounted through said side bars and through one or another of holes 45 in the links. A boiler 46 and an engine 47 are mounted on the main frame.- The Theanchorsshaft 48 of theengine is connected by sprocket gearing to a shaft 49 journaled to the trusses 13, 14. The shaft 49 is connected by sprocket gearing at each end to a shaft 50 journaled to the side bars. 10, 1 1. A drum 51 is fixed to the central portion of the shaft 50 and a cable 52 is fixed at its rear end toand is adapted'to be wound on said drum. The bight of the cable 52 extends over a sheave 53 on a shaft 54 journaled to the hounds 18, 19, and the forward end of said cable is fixed to the central portion of the forward cross bar 12-of the main frame. The shaft 50 is connected by duplicate sprocket gearings 55,

56 to a shaft 57 journaled to the trusses 13,

14 and a differential gear device, shown conventionally at 58, is provided at the center of the latter shaft intermediate of said gears. The differential shaft .57 is connected by duplicate sprocket gearing 59, 60 at its ends to the supporting tract-ion wheels 16, 17. The shaft 49is provided with a drum 61 intermediate of its ends and a sheave 62 'loosely mounted on a shaft 63 journaled to sprocket gearing 68, 69 to a shaft 70 also vance of the machine.

journaled to the sidebars. A drum '71 is mounted on the central portion of the shaft 70. The several sprocket gearings may be provided with clutch connections to their driving shafts in order that they maybe operated independently or conjunctively as desired. Any desired steering mechanism may be applied to the bolster 33 and axle 37, to turn said bolster and axle on their vertical .pivot as required to give direction to the machlne.

Any desired form ofgearing, such as spur caring or screw gearing may be substituted or the sprocket gearing shown and described.

In practical operation of the machine, the

parts being in the positions shown, the machine can be advanced on a roadway or across a field by driving the engine with connections to the traction wheels 16, 17 by'way of the shafts 48, 49, and 50, the sprocket gearing 55, 56, the differential shaft 57, the sprocket caring 59 and 60. This connec tlon may e unclutched and the machine be advanced across a swamp or marshy surface, where the traction is not suificient to move it, by attaching one end portion of a cable (not shown) to the drum 61 and extending said cable over the sheave 62 and "forwardly to attachment to an anchor (not shown) in ad- Then the drum 61 may be driven by the engine through the shafts 48 and 49 to the end ofwinding the cable on the drum and advancing the machine.

.When the machine has reached the desired location, it may be anchored as follows: The anchors 38, 39 are set at the desired angle by adjustment of the bolts or pins 43, 44 in the desired holes45; the bolts senses 26 and 31 are withdrawn; the forward portion of the main frame and load carried thereby is lowered under control of the cable 52 governed by the gearing through which it is connected to the engine; the cable (not shown) is detached from the drum 61 and attached at one end to the drum 71 and at the other end to the load to be drawn, such as a ditching machine; and the drum 71' is driven by the shafts 48, 49 and 50, the sprocket gearing 65, 66, the shaft 67, the s rocket gearing 68, 69 and the shaft 70, to the end of winding said cable on said drum. The strain of the cable (not shown) winding on the drum 71 moves the machine rearward and causes the anchors 38, 39 to enter and engage the soil on which the machine rests and pulls the forward portion of the main frame downward so that the forward cross bar 12 engages the ground or even enters-it. When the anchors 38, 39 have perfectly engaged the soil, the bolts or pins 26, 31 may be re laced to connect the main frame inflexibly to the hounds. Thereafter the strain of the cable (not shown) is exercised in drawing the load, such as a ditching machine, toward the ca stan machine.- When the load has been a vanced into contiguity to the .capstan the connection between them is detached by unclutching one or the other of the gears, the drum 51 is rotated to wind the cable '52 on the drum and lift the forward end portion of the main frame relative to the hounds and release the anchors from the ground. At the same time. the capstan machine may be advanced either by use of the traction devices or by connection to an anchor in front as described to aid in releasing the anchors 38, 39 from the soil. Or,

'the bolts or pins 43, 44 may be removed,

thus permitting the anchors 38, 39 to swing clear and draw lengthwise out of the soil during the elevation of the forward end of the main frame. It is to be understood that the bolts or pins'26, 31. are removed during the operation of lifting the forward end ortion of the main frame, and are replace to sustain the frame at the desired elevation relative to the hounds when the machine is trans orted.
